I had no problems whatsoever before this hot patch. Got the patch and started a new game this afternoon. I play for a bit and then the game hangs waiting for the next turn to start. This evening I reloaded and played for a bit and it hung again. I'm manually moving ships each turn. Support ticket has been submitted.
Edit - I just finished verifying files and it downloaded and replaced GC3.bin. I'll reload and try again.
Edit 2 - No luck. I got 3 or 4 turns further and it hung again.
